What are some alternatives to std::for_each in C++?

What are some alternatives to std::for_each in C++?

You can use range-based for loops, std::transform, or even custom algorithms as alternatives to std::for_each.

Can you explain how to use a range-based for loop instead?

Sure! A range-based for loop allows you to iterate over elements in a container like this: for (auto& element : container) { /* process element */ }.

What about using std::transform? How does that work?

std::transform applies a function to a range of elements and stores the result in another range. For example: std::transform(input.begin(), input.end(), output.begin(), func);.

Are there any performance differences between these methods?

Yes, performance can vary based on the method and the context. Range-based for loops are generally efficient, while std::transform can be optimized for specific use cases.
